Here is a playful idea built around the universal language of music. Artist Luke Jerram created the live installation called "Play Me I'm Yours" which has been touring the world since March 2008. Jerram wanted to shake life into public spaces through the use of street pianos that could be played by anyone at anytime. The pianos are all unique in their design minus one unifying phrase -- "Play Me I'm Yours". The location of the live installation can be anywhere from parks and plazas, precincts, bus shelters and train stations, schools, and even on ferries. Over 500 pianos have been installed across the world and has reached over 2 million people. Cities that are lucky enough to have the street pianos visit also receives their own website where community members can post photos and videos of their interaction with the pianos. (Here is San Jose's site from 2010)
